LOOSE-LEAF BINDER.

Application filed June 16,

To all whom it may concern Be it known that I, LOGAN W. MARSHALL, acitizen of the United States, residing at Sidney, in the county ofShelby and State of Ohio, have invented a new and useful Improvement inLoose-Leaf Binders, of which the following is a specification.

This invention relates to improvements in loose leaf binders, having foran object to provide a loose leaf binder so constructed as to rigidlysecure the binding posts employed in connection therewith in properrelative positions and against undesired sliding movement ordisplacement.

It is also an object of the invention to provide a binder of thecharacter described employing a post anchoring plate in which thebinding posts are adapted to be engaged, whereupon a locking plate orstrip is engaged with such binding posts for locking the same againstrelative movement or displacement.

Other objects of the invention will be in part obvious and in partpointed out hereinafter.

In order that the invention and its mode of operation may be readilyunderstood by persons skilled in the art, I have in the accompanyingillustrative drawings, and in the detailed following description basedthereon, set out one possible embodiment of the same.

In these drawings Figure 1 is a detail in perspective of the bindingpost locking plate or strip;

Figure 2 is a similar view of the base or anchoring plate;

.Jigure 3 is a like view of the cover plate for the anchoring plate;and,

Figure 4 is a vertical longitudinal section through the improved looseleaf binder.

Having more particular reference to the drawings, in connection withwhich like characters of reference will designate corresponding partsthroughout, the invention may be stated to comprise a substantiallyrectangular plate designated by the numeral 1, formed of metal,composition, or other suitable material and having a plurality oftransversely disposed slots or ways 2, 3 and a formed therein andopening onto one marginal portion thereof, as clearly shown in Figure 2.These slots 2, 3 and. 4:, as will be noted, are under cut orsubstantially T-shaped in cross section, the pur 1921.

pose of which will be subsequently apparent.

Cylindrical binding posts, one of which. is shown and indicated by thenumeral 5 are provided, and as will be noted, have the basal portionsthereof provided with enlargements 6, while heads 7 are formed upon theupper or remaining end of the same. The diameter of the binding posts 5and their respective enlarged basal portions 6 issuch as to permit ofsnug reception of the same in the under cut slots 2, S and 4, thusensuring their retention in vertical positions with respect to theanchoring plate 1 or at right angles thereto.

It should be noted that the transverse slots 2 and t formed in the plate1 are of substantially right angular formation or of the bayonet slottype; the right angular portion of the slot 2 being disposed in aoirection opposite to and outwardly from the disposition of the rightangular portion of the slot 4. The slot 3 isregular throughout and isarranged in parallelism with the corresponding portions of the slots 2and l. Consequently, with engagement of the binding posts 5 in the slots2-, 3 ande, one of the same will be engaged in the right angularextremity of the slot 2, while the other will. be engaged in theextremity of the straight or regular slot 3 and the re maining post willbe engaged in the oppositely disposed right angular extremity of theslot l.

With a view towards providing means for locking the binding posts 5 intheir relative positions as above set forth a looking plate or stripgenerally indicated by the numeral 8 is provided the same being formedof metal, composition, or other suitable material and corresponding inshape and. size to the anchoring plate 1. Spaced openings 9 are formedlongitudinally of the plate 8 and are adapted to receive the barrelportions of the binding posts ,5 therethrough as shown in the Figure 4.Thus, with the locking plate 8 engaged with the barrel or shank portionsof the binding posts 5 positioned in their respective slots 2, 3 and 4,it will be understood that relative movement as between said bindingposts will be prevented and in consequence, displacement thereof withrelation to the anchoring plate 1 will be likewise prevented.

As means for covering the lower side of the anchoring plate 1 andpreventing dis placement of the basal portions of the various bindingposts 5 with relation thereto, a cover strip 10 be and preferably isprovided, said strip being formed of material corresponding to that fromwhich the plates 1 and 8 are formed and being cornpl mental thereto inshape. @penings 11 are formed longitudinally tnroughout the plate 10 andare adapted to coincide with openings 12 formed in the anchoring plate1, whereby rivets or other suitable tastening devices '13 may he passedtherethrough and the two plates 1 and 10 thereby joined or united. Withthe cover strip 10 over the lower portions of the under cut slots 2, 3and t, it will be understood, hereinhe'lore set forth, that;displacement of the binding posts 5 will be prevented and furthermore,that bearing surfaces will be provided the enlarged basal portions 6 ofthe same, permitting ot their sliding. introdui'rtion into the slots 2,3 and 4% prior to engagement of the locking plate 8 over their barrel orshank portions.

From the foregoing, it will be understood that I have provided a simplebut etl'ectual form of loose leaf binder wherein the various bindingposts employed will he rigidly secured in their relative and adjustedposi tions by means of the locking plate 8. However, should it bedesired said. plate 8 may be disengaged from the shank portions of thebinding posts 5 and said bin eiling posts then disengaged from theirrespective slots 2, 3 or 4 as the case may be.

Furthermore, it is to be borne in mind that any number of the slots 2, 3or t may be employed or formed in the anchoring or base plate 1, such asconditions or preference ma dictate. However, it is essential that theoutermost of these slots be of right angular formation and that theirright angular portions be extended in opposite outwardly directions inthe manner indicated in the Figure 2, whereby with engagement of thelocking plate 8 therewith, lateral or longitudinal displacement of thebinding posts with respect to the anchoring plate will be prevented.

Manifestly, the construction shown is capable of considerablemodification and such mod'fication as is within the scope 01": myclaims, I consider within the spirit oi my invention.

I claim:

1. A loose leaf binder comprising an anchoring plate having a pluralityof ways formed therein transversely of the same and opening onto onemarginal portion thereof, certain of said ways being of right angularformation and having their angular port-ions disposed in oppositeoutward directions, binding posts having enlarged basal portionsengaged. in the extremities of said ways, and a locking plate en 'agingthe shank portions of said binding posts.

2. it loose leaf binder comprising an anchoring plate having a pluralityot ways formed therein transversely of the same and opening onto onemarginal portion thereof, certain of said ways being of right angularformation and arranged adjacent the opposite extremities of theanchoring plate hav ing their right angular portions disposed inopposite outward directions, binding posts having enlarged basalportions slidably en gaged in the extremities of said ways, and alocking plate having openings therein receiving the shank portions ofthe binding posts therein.

3. is, loose leatbinder comprising an an choring plate having aplurality oit ways formed therein transversely of the same and openingonto one marginal. portion thereot certain of said ways being oi rightangular formation and arranged adjacent theopposite extremities of theanchoring plate having their right angular portions disposed in oppositeoutward directions and in parallelism to said marginal portion of theanchoring p .te, binding posts slidably engaged in the entiemities ofsaid ways, and a locking plate having openings formed throughout he szme engaging the shank portions of id binding posts.
